Hui's KGTP tracepoints stuff is not in mainline, and at least
at the vintage of the broken kgdb, was not part of kgdb at all:

http://www.sourceware.org/ml/gdb/2010-09/msg00134.html .

It implements its own RSP handling.

(I've never heard of Jim Blandy's previous effort for tracepoints
in the kernel ending up used, or in production.)
